摘要：

The exchange interaction with nearest neighbors J1, next nearest neighbors J2 and the spectroscopic splitting factor g were determined for two orthoferrites YFeO3 and LuFeO3. A high temperature analysis of the paramagnetic susceptibility yielded the following results: For YFeO3, J1 k = -27.2 ± 1°K, J2 k = -1.2 ± 0.2°K, g = 2.05 ± 0.1, and for LuFeO3, J1 k = -24.2 ± 1°K, J1 k = -1 ± 0.1°K, g = 2.00 ∓ 0.05. Compatible values of J1 were found from the low temperature susceptibility measurements and Néel point. © 1969.
